The rats were divided into four groups, namely, control group, Pb group, Zn group, and Pb + Zn group. Animals were exposed to Pb (819 mg of Pb\/L) or Zn (71 mg of Zn\/L) or both through drinking water for 65 days. Rats exposed to Pb showed decreased weights of testes and accessory sex organs. Significant decrease in the testicular daily sperm production, epididymal sperm count, motility, viability, and number of hypoosmotic tail coiled sperm was observed in Pb-exposed rats. Testicular 3\u03b2- and 17\u03b2-hydroxysteroid dehydrogenase activity levels and circulatory testosterone levels were also decreased significantly in Pb-exposed rats. A significant increase in the lipid peroxidation products with a significant decrease in the activities of catalase and superoxide dismutase were observed in the testes and epididymis of Pb-exposed rats. Moreover, the testicular architecture showed lumens devoid of sperm in Pb-exposed rats. Supplementation of Zn mitigated Pb-induced oxidative stress and restored the spermatogenesis and steroidogenesis in Pb-exposed rats. In conclusion, cotreatment of Zn is effective for recovering suppressed spermatogenesis, steroidogenesis, elevated oxidative status, and histological damage in the testis of rats treated with Pb.<\/jats:p>","DOI":"10.1177\/0748233716637543","type":"journal-article","created":{"date-parts":[[2016,4,21]],"date-time":"2016-04-21T22:38:38Z","timestamp":1461278318000},"page":"265-276","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":53,"title":["The protective effects of zinc in lead-induced testicular and epididymal toxicity in Wistar rats"],"prefix":"10.1177","volume":"33","author":[{"given":"M Reshma","family":"Anjum","sequence":"first","affiliation":[{"name":"Department of Biotechnology, Sri Venkateswara University, Tirupati, Andhra Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P","family":"Madhu","sequence":"additional","affiliation":[{"name":"Department of Biotechnology, Sri Venkateswara University, Tirupati, Andhra Pradesh, India"},{"name":"Department of Zoology, Sri Venkateswara University, Tirupati, Andhra Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K Pratap","family":"Reddy","sequence":"additional","affiliation":[{"name":"Department of Biotechnology, Sri Venkateswara University, Tirupati, Andhra Pradesh, India"},{"name":"Department of Zoology, Sri Venkateswara University, Tirupati, Andhra Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P Sreenivasula","family":"Reddy","sequence":"additional","affiliation":[{"name":"Department of Zoology, Sri Venkateswara University, Tirupati, Andhra Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2016,7,9]]},"reference":[{"key":"bibr1-0748233716637543","doi-asserted-by":"publisher","DOI":"10.1007\/s00244-009-9371-2"},{"key":"bibr2-0748233716637543","volume-title":"Toxicological profile for lead-update.
